CONCAVE DEMOUNTABLE-RIM DISK WHEEL.

Application filed March 9, 1923. Serial No. {5..', .3,887.

The object of my invention is to produce a very simple disk Wheel decreasing the amount of material, while increasing strength and vsecuring the best service of which a disk wheel is capable, together with other detailed merits herein set forth.

Reference will be had to the accompanying drawings of which Figure 1 is a front elevation of my wheel. Figure 2 is a side sectional elevation on line 22 of Figure 1. Figure 3 is a section on line 3-3 of Figure 1. Figure 4 is a section on line 4% of Figure 1. Figure 5 is a front elevation of a portion of the rim of the wheel and disk when used with a split rim. Figure 6 is a top plan view looking at the edge of the rim in the direction of the arrow a, Figure 5. Figure 7 is a section on line 77 of Figure 5. Figure 8 is a radial section through the valve stem. Figure 9 is a section on line 99 of Figured Figure '10 is a section of the rim and margin of the disk on line 10-10 of Figure 5. Fi 'ure 11 is a section through the rim and marginv of a disk showing a modified form. Figure 12 is another section through the rim and margin of a disk show ing anothermodified 'form.' Figure 13 is another section through the rim and margin of a disk showing :1 further modified form. an 1 ,L'urcs 1 to 42 inclusive show the construclion of my disk as applied to what is known as: a quick detachable pneumatic tire T1111, a type of rim which has the main rim portion a continuous solid ring. 35 Figures 5 to 13 inclusive show the adaptation of my invention for use with'what known as a split rim.

Rims oi the quick detachable type are those in which a. ring or portion ofthe rim removed in a tire change, but with a split rim the rim is usually made in" one piece and is cult asunder or not united as a continuous ring, but is spliced by :1 detachable splice and in. making a. tire change with a split rim the rim is collapsed inward by having its l'IiflH pushed past each other afterthe connection splice disengaged and thus the r m ,made smaller by contraction and the i e removed from the outside. The terms inwardly and outwardly used herein indicate to and iron th wheel axis r.nd the term forward indicates from the car body, and rearward toward the car bodyj In the drawing, 1. indicates the hub of'an automobile wheel here shown as the rear wheel. 2 indicates the main portion of a q uick detachable rim and 3 indicates the side ring or detachable flange of the quick detachable rim. 4; indicates an ordinary brake drum and 5 indicates the integral flange of the hub 1. I prefer'to make the Web of my wheel of a concave disk shape as is indicatedby 6 and this disltis reinforced for a region around the hub by reiniorcmg disk 7, andthese two disks are spaced apart at the hub region and secured to the hub by means of a series of stud bolts 8. 1

The concave portion of the disk extends outward into contact with the rim 2 at the point 9, and from this point 9 the disk is turned forward somewhat upon itself into the flange 10. This flange 10 abuts the inclined portionll of the quick detachable rim 2 and the rim is seated on the flange portion 10 and the seat portion 9 of the disk 6 and is held in place against lateral displacement by the clamping member l2. The normal section of this clamping" member, here shown as a ring 12, is shown in Figure 4. Other sections adapted to the securing in place of particular types of rims are indicated. at .12 in Figs. 7, 8 and 10, at 12 in Fig. 9, at 12 in Fig. 11 and at 12 in Fig, 13. A series of bolts 13 having their nuts 14. seated on bosses 15 01 the ring 12, pass through the ring and through the disk and have their heads 16 seated in slight depressions in the back of disk 6 and thus clamp the ring 12 in place, holding the rim securely on to the margin of the disk.

For purposes of What is called outside inflation a portion of the disk at 16. is indented where the air valve passes through (see Figs. 1 and 3) and thus the air valve may he reached from the front face'of the wheel. The ring 12 is also pierced :t'or'the entrance oi this air'valve 17, the latter being shown in dotted lines.

The split rim shown in Figures 5 to 9 inclusive and indicated by 18, is spliced by means of a splice plate 19, having edges 20 turned over on all four sides, and these edges 20 embrace the sides and ends of a pair of blocks 21, which are permanently secured by rivets to the ends of the rim ring 18. The

r tnally prevents lateral a well as circumferential relative displace: it thus rendering thebloclis and rim ends siracticz'rlly unitary.

The riin shown as provided with an integral inwardly extending portion or rib, tor cooperation with the disk flange in fastening the rim on the dial; This rih or inwardly extending); portion of the rib may be constituted. ot' the riuatrough or gutter 11 t l to -Z. or tin supplemental rib 24; of to 1'2, or the depressed rib Q5 of Fig. 13. In each case the inclined or oblique rear side oi the rib-like portion coacts with the peripheral flange it) of the disk to hold the rim securely under the clamping action of the ring or tiang c 12 The (ii,- periphery, while. turned forwardly and inwardl in all c- 5 1" shown at 9 and i in Figs. ill 12 and 1.3 it l.-' further cxtended to: .irdly to proride thc substantially axial prolongation 25 the angles iug slightly less prominent in ig. 13 as indicated atit a and 26 The t'lfllill fi lllg ring or flange 12 stl'VCS in all cases to press the rim rearwardl against the flange of inc disk. In Figs. 1 to 11. and l3 the clamping: ring contacts directly the rib ot the rim, whereas in Fig. 12 it contacts the rim in 'l'ront: or" the rib. the t'unctio'ning being the same.

ine point is to carry the run on the dish on the forward curved portion of the disk, as represented by the portions or flanges t), 10 and E26, and to clamp against these poi tions or t lang os the rib-like inward projections 11, 2% or ll this outwardly and forwardly curved form of the disk I am able to use slightly less metal in the disk and yet provide for what is called outside inilatio'n tor the air stem or; the pneumatic tire.

In using: a split. rim on a narrow contact line, as l har indicated. it is desirable that, th rim should he quite s curely fastened at the spli -cared this splice plate ll) with its aide thing 1t). emln'a ing on four sides the i i-W its 2}, h his the splitcnds ot th rim i l fllit"l!l' independently of the s r ws '12:),

\ icli is a great desidcratnin.

The forwardly curved lianjic on the. margin oi the dish results in lllktltlllji a str nger marginal flange or a conc we wheel than is obtained by reverse bending of th in the margin of the disl. It: quite a stress upon the :"etal to bend itrearwardly enough to permit outside inflation and then for-- wardly for rim contact and then make a reverse rearward turn on the margin tor producing a flange for supporting the rim jill nlr and thus the flange turned inwardly and forwardly on the margin of my concave disk is an important feature.

The depression in the rim 18 serves the same purpose as the projection 2i and that. permits the rim 18 to be made out of flat stock metal instead of a special rolled section that is required with the projection 24, which is a great desideratuin since many steel mills are equipped to make fiat stock strips While special sections are special work with the less number of opportunities tor purchase of the material.

The clamping or splice plate 1.9 furnishes a secure fastening for the split rim ends against displacement in every direction, due to the overturned edges of the plate embrao ing on all sides the blocks 21 which are per nianentl v secured to the split ends of the rim 18.

The clamping ring 1 may be shaped in an; suitable form and instead of having the bolts 1?) horizontally ar 'anged 1 may arrange the bolts in a diagonal position as indicated hv dotted lines of the bolt in Fig. lll. This inclined position of the bolt 30 .uialtcs unnecessz ry as deep a depression in the ring as indicated byf31 for a seat for the bolt 13, see Figure 7. I

In place of the ring 12 I may use clips of any suitable form at the location of the bolt depending on the wish of the user of the wheels.

The arrangement of the disk connection to the rim is such that it HIUOUDlS'fO substantially a line or limited surface contact and since that is the case the clamping means will always obtain a good lit; between the rim and the disk whereas in other cases where the. rim is intended to lit at two or more zones of circumferences an exact, fit ol these two zones is easily obtained and there results a slight movement at some points causing a squeak of tho'parts, but with the contact as l have, provided this fault is overcome lVlia'L I claim is:
